Concrete Waterproofing
AmTech uses crystalline waterproofing systems including Port Seal® and Xypex to address cracks, joints, honeycombing, pipe penetrations, and active water infiltration in concrete tanks and structures.
Protect concrete tanks from water infiltration, chemical exposure, cracking, and long-term deterioration with engineered lining and waterproofing solutions. AmTech evaluates each structure, repairs damaged concrete, and selects systems suited to potable water, wastewater, fire suppression, and industrial applications. Northeast projects receive field-engineered service designed to support tank integrity, safe storage, and reduced operational disruption.

Engineered concrete tank lining, sealing, waterproofing, repair, and corrosion protection for demanding water and industrial environments.
AmTech uses crystalline waterproofing systems including Port Seal® and Xypex to address cracks, joints, honeycombing, pipe penetrations, and active water infiltration in concrete tanks and structures.
Hot and cold water tank lining combines inspection, concrete or steel repair, surface preparation, and HydraStone Alkrete® cementitious lining for water storage and thermal tank environments.
DuraChem® 500 series poly lining creates a seamless barrier bonded to concrete, helping protect wastewater tanks from fluctuating pH, hydrogen sulfide exposure, biological activity, and abrasion.
Concrete tank waterproofing helps limit water permeation, leakage, efflorescence, rebar corrosion, and deterioration. AmTech assesses the substrate, repairs damaged areas, and applies a system suited to the tank’s stored contents and service conditions. Crystalline products such as Port Seal® and Xypex react with moisture inside the concrete matrix, while lining systems provide additional protection for water, wastewater, and industrial applications throughout the Northeast.

AmTech combines field engineering, proprietary systems, and experienced crews for demanding tank restoration projects.
Decades of tank lining and repair experience support informed decisions for complex concrete structures.
Own experienced field crews support projects across the All 50 US States, Canada, and Caribbean.
Material selection considers substrate condition, stored contents, and the Northeast project environment.
Application methods and repair planning are designed to support quick restoration of operations.
Engineer-led professionals support complex tank lining and waterproofing projects.

CS Project Engineer / NLPA Special Inspector
Greg Comeau serves as AmTech's CS Project Engineer and NLPA Special Inspector, bringing specialized expertise in commercial tank assessment, regulatory compliance, and complex lining system design. As a licensed NLPA Special Inspector, Greg conducts detailed tank integrity evaluations, ultrasonic permeation testing, and structural assessments that form the foundation of every AmTech project. His engineering oversight ensures that surface preparation, material selection, and application protocols meet or exceed API, NFPA, ANSI, and NSF standards. Greg manages projects across multiple industries—from Fortune 500 chemical facilities to municipal water systems—coordinating field crews, specifying proprietary lining systems, and providing technical guidance throughout the installation process. With direct oversight of both routine maintenance projects and emergency response situations, he ensures that every tank restoration delivers maximum service life extension while minimizing facility downtime. Greg is the primary contact for project inquiries, technical consultations, and employment applications.
Concrete tank liner costs vary according to tank size, substrate condition, access, stored contents, existing coating removal, repairs, surface preparation, and the lining system specified. A project may involve inspection, concrete restoration, waterproofing, or a complete lining application. AmTech evaluates these conditions case by case so the proposed scope reflects the tank’s actual requirements rather than using a generic price.
